When I fought Aragon their army was bigger than expected. An entire army was wiped out and the only other remaining one in the entire Iberian Peninsula was down to 4000 men. Just as I was moving my North African armies (2 stacks, 10,000 each), the Aragonese navy was right next door, about to pounce. Thankfully the war ended right then and there (I was not the starter nor defender of the war.) I might recall a North Africa army in the future to fight the Aragonese, but constantly Morocco and Algiers declare war. I can't make any deals except for annulling of treaties and conceding defeat otherwise my huge infamy skyrockets again. Right now though I am into a Milan game trying to unite the HRE, very challenging. The good part is that I am allied with the HRE since the first 10 years, and both of us have been nerfing Europe lately. I hope for electors to realize how bad they are and vote for me instead. Our best war was nerfing Austria into 3 provinces and freeing Tyrol and Styria. But Bavaria came in and fought Tyrol, my coalition beat them back but they took control of my Tyrol. They vassalized them in a separate deal. The same day I declared war on Tyrol to overthrow the Bavarian regime and put mine back in. Very bad time to by Tyrolian, having two countries fight on your soil for control of it. I managed to free Tyrol, and then vassalize them. Then the Sytyrians came in, but thankfully war did not break out and they withdrew within 4 months. Very interesting last few years in the HRE.
